VQ-Decoder Validation Kit(dvc)

Decoder Validation Kit (DVK)

AVS3 Elementary Streams

Design
Validate
Improve

DVK is

  • A Video Decoder Certification
  • A powerful validation environment for VVC, AVS3, AV1, HEVC, VP9 Decoder developers
  • A comprehensive set of test bitstreams, a configurable encoder, and analytic tools to verify decoder compliance to a standard
  • A tool that allows comparing test decoder’s output with «known correct» results
  • An instrument to determine anomalies in decoder design to save validation and support costs

Advantages

  • The ability for a user to generate own streams with Configurable encoder
  • Configurable Encoder is 100x faster than a Reference (HM, VTM et al) encoder
  • Create test bitstream with restrictions to hardware design for the current stage of development
  • Kit of additional tools - Configurable encoder, Coverage & Analytic
  • 1-year free support

Syntax - handy tiny size (small resolution and 1-2 frames only) to maximize coverage of each syntax element and cross-coverage of essential pairs. One test stream - one feature, make individual «coding block» design independently. Good for initial RTL design.200streams *400streams *438streams *876streams *
Stress - include all the features covered by the Syntax streams, in higher resolution and more frames. Good for an advanced stage of decoder design.36streams72streams36streams72streams
Performance - test the limits of the hardware decoder’s speed. Good for final validation to prove compliance to Level requirements.400streams800streams1656streams3312streams
Error resilience - set of non-fully-compliant bitstreams to test decoder’s robustness to errors and ability to recover. Good for final validation to deliver viable end-user product.0streams0streams0streams0streams
* Stream counters can change, since product is under development

Tools

  • Configurable encoder - to allow the Customer to create their own test stream combination (from syntax to error resilience)
  • Residual randomization - test limits of transform and quantization which are hardly achievable with the natural encoding process
  • Override - determine a scenario you want for a block with the Override feature, making an exception from a pattern
  • Coverage Tool - how the provided streams cover all cases. Compatible with streams.
  • Analytic (Collector, Reporter, Differ, Analyzer) - graphical representation of syntax coverages, speed up test cycles by reducing the streams and their number, compares the stream coverage
